The Kydex body on the Infidel Ultra Max provides a rigid material that is custom fit to each firearm and maintains its shape even with the pistol un-holstered. The smooth, low friction surface allows for a fast draw and easy one-handed re-holstering of the firearm. The all-Kydex body will not bend or stretch over time and is impervious to sweat and solvents.Infidel Ultra Max – Sig P365
